I was able to locate the Relay, which is a solid state relay on my fridge, Where can I get the SSR tested?

I cannot see the Overload Protector, is it possible to not have one on a fridge?

Here is what I see under my fridge:

Wiring Harness-->2 round things on top of these plastic things with tubes coming out for water-->Connection to a Fan-->Connection to the relay and some flat piece connected to the motor for the red wire to connect.

Sorry, if this is not very technical terms, I am a computer geek by trade.
